An Orlando police officer was killed in the line of duty Monday morning, the department said, and county officer was killed in a motorcycle crash during the ensuing manhunt for the suspect.

Orlando police Master Sgt. Debra Clayton was shot by Markeith Loyd, 41, after she spotted him outside of a Walmart around 7:15 a.m., police chief John Mina said. Clayton returned fire, according to authorities, but it is not believed that she hit Loyd.

Loyd was wanted in connection with the December slaying of his pregnant ex-girlfriend, Sade Dixon, 24.

After shooting Clayton, authorities said Loyd fled toward the Pine Hills neighborhood, where he fired shots at a deputy’s cruiser and carjacked a vehicle.

A massive manhunt has been underway since about 8 a.m. During the search for Loyd an Orange County motorcycle deputy was killed when another vehicle turned out in front of him. The sheriff's office said Monday that he is 35-year-old Deputy First Class Norman Lewis.

As of 3:15 p.m. Loyd remains at large.

During an afternoon news conference Orange County Sheriff Jerry Demings urged Loyd to turn himself in. Demings said the best thing he could tell the suspect is to surrender so the situation can be resolved peacefully.

Orlando Mayor Buddy Dyer declared Monday an official day of mourning. Florida Gov. Rick Scott said he was "heartbroken and angered" over the loss of lives.
